 Authorised heating diagrams: See heating diagrams enclosed.
The layout of the heating circuits' accumulators, pumps and mixers has to be
designed according to legislation by the installer.
D A N G E R
Danger of suffocation due to odorless carbon monoxide in the storage room
• Ventilate sufficiently before entering the fuel storage room
• Keep window/door open during stay
• Position second person outside to supervise
Dust explosions in the storage room due to the explosive combustion of
dust (pellet dust)
• Pay attention to proper grounding of the pellets transportation tubes
• No motors in the fuel storage room
 Except agricultural buildings
• No other source of ignition (e.g. light) in the storage room
• No electrical equipment (e.g. light switch) in the storage room
• No welding works in dusty environment
